I am truly no expert either, just an experienced amateur ??
All theses codes are css, which you can try out and remove very easily in the customizer > extra css.
Just copy paste them, and remove or modify them. You can see the result immediately on the right, and if you don’t like the result just click on the X in the left top, then it saves nothing, and you can start anew by clicking “customizer”.
If you like it, then click save.
You can always change or remove it afterwards.
If you do a lot of modifications you can also put them in (or transfer them to) the css file in the child theme.
